Help I and my mechanic are at a loss.

Car was running fine then after a half hour break in a journey it died after about 300 yards. Dash displayed as if it had stalled but it wouldn't restart. Engine turning fine. RAC find nothing wrong. Every fuse and relay checked. No fuel being pumped.

Person mechanic gets it started by jumping it. I changed the battery after seeing comments on the ecu not turning the lift pump on if the voltage is a bit low but still nothing.

Next step was to change the lift pump which was much easier than I was worried it would be but still nothing.

I get a voltage on the end of the plug when I turn the key but when it's connected to the pump it's like it's shorting out.

I have tested both the old and new pumps and both are running fine.

Mechanic is recommending I get an auto electrician in but they are bloody expensive. I'm an electrician myself but I don't have a clue what's next.

Your advice would be greatly appreciated.

you need to scan it with VCDS  to see if the ECU's have logged any faults for starters ! cheers Stuart

Sorry I should have mentioned that I have used an obd scanner and there are no fault codes.

Not something similar like a corroded ground wire or something, I don't know much about Skodas yet but on a previous car owners club a few people had a problem where a ground from the gearbox had corroded and caused starting problems?

Corroded earth it was. I ran a temporary one from the block in the drivers foot well and the pump ran. New wire in and no problems since. It has also sorted out the idle shudder I was getting. Thanks all
